>I'm confused. You seem to be suggesting that extra-curricular activites are in fact an accurate indicator, contrary to the SAT proponents?
I'm unsure how you arrived at that conclusion. I'll chalk it up to me being unintentionally unclear.
What I am saying is that its largely a fallacy that Universities are commonly put to the decision of a more social candidate versus a more academically talented candidate.
The more common reality being that the leading academically talented candidates are as or more qualified in their extra-curricular participation.
At least within a deviation of academic and social metrics that is meaningful.
Selectivity of admissions allows for selectivity of curriculum. Selectivity of curriculum allows for better trained / educated students.
As well as tailoring of education to meet a student's ability, both on the high and lesser ends.
You may as well ask what the purpose of special education or gifted programs are. To put in in the terminology of those commonly concerned with the plight of haves and have nots, the answer is educational justice.
Last, maximizing the education of elite academic performers tends to maximize results for the nation in the real world in a manner that raises the living standards for have nots.
